[0049] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application with reference to the accompanying drawings.

[0050] The following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] In the description of the present application, it should be understood that the terms "first", "second" and the like are used only for the purpose of description and can not be understood as indicating or implying relative importance. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" means two or more. "And / or", the association between the associated objects, means that there can be three kinds of relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B, and the existence of B alone. The character " / " generally represents the relationship between the front and rear associated objects is "or".

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0053] The first aspect of the present application proposes a pure drinking system, which is a comprehensive system integrating water purification and convenient drinking water functions. The pure drinking system can be applied to places such as homes, offices, schools, hospitals, etc. The embodiments of the present application do not make specific limitations.

[0054] Please refer to Figure 1, the pure drinking system comprises a water purifier 3 and a water tank-free pipeline machine assembly. The water purifier 3 has a raw water inlet 31 for connecting tap water, and the water purifier 3 is used for deep filtration and purification treatment of tap water, so that the water quality of the water source meets the standard of safe drinking or meets the specific use requirements. The working principle of the water purifier 3 usually includes pre-filtering, precision filtering and post-treatment, etc. The pre-filtering mainly filters out large particles in tap water by using a filter screen; the precision filtering uses more advanced filtering technology to remove small molecules, harmful substances, etc. in tap water, and the post-treatment may include activated carbon adsorption, etc. to improve the taste of water. The water purifier 3 also has a pure water outlet 32, and the water tank-free pipeline machine assembly is in communication with the pure water outlet 32, so that the purified pure water in the water purifier 3 can flow from the pure water outlet 32 to the water tank-free pipeline machine assembly, and the water tank-free pipeline machine assembly is used for instant heating or refrigeration of the purified pure water, so as to accurately obtain drinking water for the user and meet the different drinking water temperature requirements of the user.

[0055] Please continue to refer to Figure 1 In some embodiments, the pure drinking system can also include a faucet 4, which can be directly connected to the water purifier 3, so that the faucet 4 can directly flow out the purified pure water in the water purifier 3. Further, considering that the water pressure in the water supply pipeline for providing tap water to the water purifier 3 may change due to various factors (such as water supply peak period, pipeline maintenance, etc.), a pressure reducing valve is usually configured before the raw water inlet 31 of the water purifier 3, which not only stabilizes the water pressure in the water supply pipeline and reduces the water pressure entering the water purifier 3 in advance, avoiding physical damage to the water purifier 3 due to high water pressure. In order to distribute the purified pure water to the water tank-free pipeline machine assembly and the faucet 4 at the same time, improve the utilization efficiency of water, the pure water outlet 32 of the water purifier 3 is usually configured with a flow dividing valve, and the water inlet end of the water tank-free pipeline machine assembly and the water inlet of the faucet 4 are in communication with the flow dividing valve. When the user needs to take temperature-adjusted drinking water, such as 5℃-15℃ ice water in hot summer, or 40℃-50℃ warm water for washing milk powder, or 90℃-99℃ hot water for tea, the user can open the water tank-free pipeline machine assembly for use. When the user needs to take domestic water to wash tableware or wash vegetables and fruits or wash clothes, the user can open the faucet 4 for use.

[0056] Please continue to refer to Figure 1However, the independent pressure reducing valve and the flow divider are respectively installed in the water purification system, which occupies more space and causes the pipeline layout to be messy, increasing the installation difficulty. Moreover, when a fault occurs, the pressure reducing valve and the flow divider need to be detected and repaired separately, and the replacement of the pressure reducing valve and / or the flow divider in the limited space will greatly increase the operation complexity and maintenance cost. Therefore, in view of the existing problems, the water purification system can further comprise a flow divider 1, wherein the faucet 4, the tankless pipeline machine assembly, the water purifier 3 and the tap water supply pipeline are all connected with the flow divider 1, so that the tap water supply pipeline can introduce tap water to the flow divider 1, regulate and maintain the excessively high and unstable water pressure of the tap water in the tap water supply pipeline within a preset pressure value range, finally generate stabilized water, and deliver the stabilized water to the water purifier 3, which generates pure water after deep filtration and purification treatment of the stabilized water. The pure water purified by the water purifier 3 can flow into the flow divider 1, and then be introduced to the tankless pipeline machine assembly and the faucet 4 respectively through the flow divider 1. The pure water flowing to the faucet 4 will be used as domestic water, and the pure water flowing to the tankless pipeline machine assembly will be drunk as direct drinking water.

[0057] In the related art, the pipeline machine is used in cooperation with the water receiving box to carry residual water flowing out of the water outlet nozzle, so as to prevent water droplets from splashing or polluting the surrounding environment. However, the existing water receiving box design has certain limitations, and the application scene is relatively single, and cannot be flexibly adapted according to different use scenes.

[0058] To solve the above problems, please refer to Figures 2 to 4 The application further provides a tankless pipeline machine assembly. In the embodiment of the application, the tankless pipeline machine assembly comprises a tankless pipeline machine 2, a wall hanging piece 6 and a water receiving box 7.

[0059] The tankless pipeline machine 2 has a water outlet nozzle 212 through which drinking water flows out for use by a user. In the tankless pipeline machine 2 according to the embodiment of the application, since it is designed without a water tank, on the one hand, it does not occupy too much space, so as to realize miniaturization of the tankless pipeline machine assembly, and on the other hand, since the tankless pipeline machine 2 does not need to store water, it is not necessary to maintain the water temperature of the water tank, thereby reducing energy consumption and avoiding the problem that bacteria are easily bred in the traditional pipeline machine with a water tank, and thus improving the water quality of the tankless pipeline machine 2.

[0060] The wall hanging piece 6 is used to be installed on the wall surface of a mounting object. The mounting object can be a wall or other structural surface, such as the surface of an integrated cooker, etc. For the convenience of description, the mounting object is taken as a wall in the following. It should be noted that the wall hanging piece 6 has multiple fixing modes, and can be fixed on the wall by screws or other connecting members to ensure the stability of installation, or other suitable fixing modes, such as adhesion, buckle connection, etc. can be adopted to meet the installation needs of different users and the characteristics of the installation environment.

[0061] The water receiving box 7 has a water containing cavity 7A and a water leakage hole 721 communicating with the water containing cavity 7A, and the outer wall of the water receiving box 7 is provided with a plug-in groove 712. The water receiving box 7 can be selectively placed on the table top or plugged and fixed with the wall hanging piece 6 through the plug-in groove 712, so that the water leakage hole 721 is located below the water outlet nozzle 212. Among them, the water receiving box 7 provides a stable support platform for the placement of the water container. When the user needs to receive water, the water cup, kettle and other water containers can be placed on the water receiving box 7, so that the water container can be accurately placed below the water outlet nozzle 212, and the water outlet nozzle 212 can be conveniently received. The water outlet nozzle 212 flows out. Even if a small amount of water splashes during the water receiving process, it will flow into the water containing cavity 7A through the water leakage hole 721, avoiding wetting the surrounding table top or ground. The overall shape of the outer contour of the water receiving box 7 is relatively diverse. It can be designed as a cylindrical shape, which has a relatively smooth appearance and is suitable for some environments that pursue a simple style. It can also be designed as a rectangular body. The rectangular water receiving box 7 can be more efficient in space utilization, and can better coordinate with the surrounding equipment in some regular installation environments.

[0062] In addition, the wall hanging piece 6 can be designed as a whole rectangular frame structure, and the slot of the plug-in groove 712 is also designed as a rectangular opening. This matching design makes the water receiving box 7 and the wall hanging piece 6 more compatible when plugged in, enhancing the stability and reliability of the connection. The regularity of the rectangular structure also facilitates production and installation, improves the production efficiency and installation convenience of the product, and further improves the overall practicality and aesthetics of the water tank-free pipeline machine 2 assembly.

[0063] The water tankless pipeline machine 2 assembly and the purified drinking system based on the embodiments of the present application have the following advantages. The water receiving box 7 is provided with a water containing cavity 7A, a water leakage hole 721 and an outer wall provided with a plug-in slot 712. The water receiving box 7 has a flexible placement mode and can be placed on a table or fixed by plug-in with the wall hanging piece 6 through the plug-in slot 712 of the outer wall. In actual use scenarios, when the use environment has a spacious and suitable table, the user can conveniently place the water receiving box 7 directly on the table to meet the daily use requirements. When the use space is limited, the table space needs to be saved or the wall hanging installation mode is adopted for the consideration of layout aesthetics, the water receiving box 7 can be stably plugged in with the wall hanging piece 6 through the plug-in slot 712 of the outer wall. The diversified placement mode effectively solves the problem of single application scenario of the existing water receiving box 7 and greatly enhances the adaptability and flexibility of the water receiving box 7 in different use scenarios. Regardless of the placement mode of the water receiving box 7, the water leakage hole 721 can be accurately located below the water outlet nozzle 212. In this way, when water flows out of the water outlet nozzle 212, residual water droplets can flow into the water containing cavity 7A of the water receiving box 7 through the water leakage hole 721. The water containing cavity 7A is like a reliable “storage container” that collects the residual water properly, avoids water droplets from splashing into the surrounding environment, prevents problems such as table dampness, ground water stains and slipping caused by water droplets, and avoids pollution to the surrounding environment, thereby creating a cleaner, safer and more comfortable use environment for the user.

[0064] Reference Figures 3 to 5 In some embodiments of the present application, the water receiving box 7 includes a box body 71 and a box cover 72. The side wall of the box body 71 is provided with a plug-in slot 712, and the upper end of the box body 71 has an open port 711. The box cover 72 is detachably connected to the upper part of the box body 71 and is used to cover the open port 711 to form a water containing cavity 7A with the box body 71. The box cover 72 is provided with a water leakage hole 721. The detachable structure of the box body 71 and the box cover 72 enables the user to clean the box body 71 and the box cover 72 comprehensively, ensuring hygiene and unblocking the water leakage hole 721 to prevent odor and bacterial growth. The box cover 72 covers the open port 711, reduces the entry of foreign matter from the outside, reduces the probability of bacterial growth, and ensures the health of the water receiving environment. In terms of use function, the water leakage hole 721 of the box cover 72 can accurately receive residual water, avoid water accumulation and spilling, and be tightly connected and not easy to overflow when shaken and collided. In addition, the design has good replaceability, and the components can be replaced individually when damaged, reducing cost and improving resource utilization.

[0065] Further, the edge of the open hole 711 is connected with the outer wall of the insertion slot 712. This design can further utilize the space in the box body 71, effectively increasing the water storage capacity of the water receiving box 7. Generally, the insertion slot 712 occupies a certain space on the side wall of the box body 71. If the edge of the open hole 711 is connected with the outer wall of the slot, it means that the space limitation caused by the conventional layout can be broken through, and the water containing cavity 7A can expand to the originally relatively idle surrounding area of the insertion slot 712. In this way, the internal water containing space of the water receiving box 7 can be increased without increasing the overall external size, and more residual water flowing from the water leakage hole 721 can be accommodated. This is particularly important for scenarios where the water outlet nozzle 212 has a lot of residual water when the water tankless pipeline machine 2 is frequently used, reducing the frequency of the user emptying the water receiving box 7 and improving the convenience of use. Moreover, this space utilization method makes the structure of the water receiving box 7 more compact and reasonable, further optimizing the practicality and functionality of the product on the basis of ensuring the water receiving function and other advantages, and providing a better user experience.

[0066] Optionally, in combination with the above description Figures 3 to 5 , the water leakage hole 721 comprises a first water hole 7211 and a plurality of second water holes 7212 connected thereto, the opening of the first water hole 7211 is larger than that of the second water hole 7212, and the plurality of second water holes 7212 are arranged on the same side of the first water hole 7211. The water receiving box 7 can be placed on the table or fixedly connected with the wall hanging piece 6 through the insertion slot 712, and the first water hole 7211 is arranged opposite to the water outlet nozzle 212.

[0067] The first water hole 7211 with a larger opening opposite to the water outlet nozzle 212 can efficiently receive large water flow or fast dripping water droplets from the water outlet nozzle 212, avoiding water splashing out of the water receiving box 7 and ensuring that most of the water can flow smoothly into the water containing cavity 7A. The plurality of second water holes 7212 with small openings on the same side or circumferential side of the first water hole 7211 can play a role when the first water hole 7211 receives water flow that is temporarily congested or has a small amount of splashing water, and can further improve the water receiving efficiency and accuracy. Moreover, this combined water leakage hole 721 design can adapt to different water flow and speed conditions, whether it is fast water or slow dripping water, it can effectively cope with it. In addition, the water receiving box 7 can be placed on the table or the wall hanging piece 6, and the first water hole 7211 is arranged opposite to the water outlet nozzle 212, so that the water receiving box 7 can accurately receive water in different placement modes, enhancing the applicability and flexibility of the water receiving box 7, meeting the user's use demand in different scenarios, and ensuring the stability of the water receiving process and the cleanliness of the surrounding environment.

[0068] Further, the upper end of the box body 71 and the opposite surface of the second water hole 7212 are provided with a plurality of protrusions 713. The plurality of protrusions 713 are arranged at intervals, and at least one protrusion 713 extends at least partially out of one second water hole 7212. The arrangement of the protrusions 713 has multiple effects. When water flows in from the second water hole 7212, the protrusions 713 can act as a certain buffer and disperse the water flow. During the water receiving process, the flow rate and flow volume of the water may fluctuate, and part of the water flow impacting on the protrusions 713 will change its flow direction and speed, avoiding the water flow directly vertically impacting the bottom of the water containing cavity 7A to cause water splashing. Moreover, this buffering effect can reduce the pressure of the water flow on the bottom of the water containing cavity 7A, reducing the possibility of noise generated by the water flow impact, creating a quiet use environment for the user. At the same time, the plurality of protrusions 713 arranged at intervals can block larger impurities from entering the water containing cavity 7A to some extent, having a preliminary filtering effect, helping to maintain the cleanliness of the water containing cavity 7A, and reducing the frequency and difficulty of cleaning. More importantly, the protrusions 713 can also be used for anti-skid. When the user places a water cup, a kettle or other water container on the water receiving box 7, the protrusions 713 contact the bottom of the water container, increasing the friction between the two, and improving the stability of the water container. In this way, even if there is slight shaking or accidental touching during the water receiving process, the water container is not easy to tip over, avoiding the water spilling out and wetting the surrounding environment, further improving the convenience and safety of use.

[0069] With reference to Figure 5 Optionally, the upper end of the box body 71 and the opposite surface of the first water hole 7211 are arranged in a direction close to the cavity bottom of the water containing cavity 7A. In this way, the flow direction of the water flow can be optimized. When water flows in from the first water hole 7211, the inclined surface will guide the water flow to flow naturally along the inclined surface to the bottom of the water containing cavity 7A, avoiding the accumulation of water on the upper end of the box body 71. In this way, not only can the water flow more smoothly into the water containing cavity 7A, improving the water receiving efficiency, but also can further prevent water from spilling out of the water receiving box 7. Moreover, this inclined design makes the space utilization of the water containing cavity 7A more reasonable. During the water receiving process, the water will first fill the space at the bottom of the water containing cavity 7A, and then gradually fill the entire water containing cavity 7A as the water level rises, avoiding the hygiene problem caused by local water accumulation. In summary, the design of the protrusions 713 and the inclined surface cooperates with the previous design of the water leakage hole 721 and the placement method of the water receiving box 7, further improving the water receiving performance, hygiene status and use experience of the water receiving box 7, so that the water tankless pipeline machine 2 assembly can stably and efficiently operate in different scenarios.

[0070] With reference to Figure 2In some embodiments of the present application, the bottom surface of the box body is arranged in a plane. The plane bottom surface can be in close contact with the placement surface such as a countertop, a wall-mounted component 6, etc. When the water receiving box 7 is placed, such close contact allows the water receiving box 7 to be more stable on the placement surface and not to be easily shaken or tipped over. Even if the user accidentally touches the water receiving box 7 during the water receiving process or generates a certain impact force when placing the water container, the plane bottom surface can ensure that the water receiving box 7 always remains in place due to its good stability, thereby avoiding splashing of water out of the box due to shaking and preventing the surrounding environment from being wet and dirty, thus creating a clean and orderly use environment for the user.

[0071] Optionally, the box cover 72 is made of stainless steel. The stainless steel material has excellent corrosion resistance. In daily use, the water receiving box 7 often comes into contact with water and various substances that may be contained in the water. The box cover 72 made of ordinary material is easily corroded and damaged, affecting the service life and hygiene of the water receiving box 7. However, the stainless steel material can resist the corrosion of water and other substances, ensuring that the box cover 72 will not rust or be damaged for a long time, effectively prolonging the overall service life of the water receiving box 7. In addition, the stainless steel material is easy to clean. The smooth surface makes it difficult for stains to adhere. When the box cover 72 is stained with water stains, dust or other impurities, the user can easily clean it by wiping it gently with a damp cloth, keeping the box cover 72 clean and hygienic. At the same time, the stainless steel material has a relatively beautiful appearance and a certain metallic texture, which can improve the overall aesthetics of the water receiving box 7, making it not only meet the functional requirements but also compatible with various decoration styles, thereby enhancing the practicality and ornamental value of the product.

[0072] Referring to Figures 3 to 5 In some embodiments of the present application, the water receiving box 7 further comprises a protective sleeve 74, which is sleeved on the side of the box body. The protective sleeve 74 is made of metal material. The metal protective sleeve 74 can provide reliable physical protection for the box body 71. During the daily use of the water receiving box 7, it can effectively resist external force impact such as collision and scratching, reduce the risk of damage to the box body 71, and avoid affecting the normal use and service life of the water receiving box 7 due to damage to the box body 71. The metal material itself has good strength and hardness and can withstand a certain degree of external force without deformation, thereby ensuring the structural integrity of the water receiving box 7. At the same time, the metal protective sleeve 74 also has good corrosion resistance and can prevent the box body 71 from contacting corrosive substances in the surrounding environment. Especially when the water receiving box 7 may come into contact with water and some corrosive impurities, the protective sleeve 74 can provide isolation protection for the box body 71, avoid corrosion and rust of the box body 71, and maintain the cleanliness and hygiene of the water receiving box 7. In addition, the metal protective sleeve 74 can also improve the overall aesthetics of the water receiving box 7. The unique texture and luster of metal make the water receiving box 7 look more upscale and durable, which can better integrate into different use environments and meet the dual needs of users for product aesthetics and practicality.

[0073] The following is a detailed description of the tankless water dispenser 2.

[0074] The tankless water dispenser 2 may include a housing 21, which is usually made of high-density polyethylene or other high-quality plastic materials. Because this material has the characteristics of high strength, wear resistance, acid and alkali corrosion resistance, waterproofing, and shock resistance, it can maintain stable performance in various harsh environments, thus ensuring the normal operation of the tankless water dispenser 2.

[0075] Please see Figure 6 , Figure 7 The tankless water dispenser 2 includes an electrical control device 24, an instant heating device 25, and a power cord 26. The power cord 26 is electrically connected to the electrical control device 24 and the instant heating device 25 to supply power to them. The electrical control device 24 is electrically connected to the instant heating device 25 to control its operation. The instant heating device 25 typically uses an electric heating element to rapidly heat the water flow. That is, when a user needs hot water, the instant heating device 25 operates. At this time, the water flow passes through the electric heating element in the instant heating device 25, and the water flow is quickly heated to a set stable temperature to achieve hot water output from the tankless water dispenser. Furthermore, the use of an instant heating device 25 to heat the water flow in this embodiment can improve the energy efficiency of the tankless water dispenser 2; that is, the instant heating device 25 adopts instant heating technology, and when the user needs hot water, the tankless water dispenser 2 can discharge hot water at the set temperature according to the user's needs. In this way, on the one hand, heat loss can be reduced, and on the other hand, the user does not need to wait for the hot water to heat up, thereby saving the user's water connection time.

[0076] Furthermore, this application does not specifically limit the type of instant heating device 25. Exemplarily, the instant heating device 25 can be one of three types: quartz tube heating, thick film heating, and electromagnetic heating. Quartz tube heating uses a quartz tube as the heating element, with a heating wire wound around the outer wall of the quartz tube. Current is used to heat the water flow inside the quartz tube, and this heating method has advantages such as fast heating speed, high temperature resistance, and corrosion resistance. Thick film heating uses thick film heating technology to directly print the heating element onto the heating element, forming a uniform heating film. This heating method features high heating efficiency, fast thermal response, and long service life. Electromagnetic heating utilizes the principle of electromagnetic induction, generating eddy currents within the heating element through an electromagnetic field, thereby heating the water flow. This heating method has advantages such as uniform heating, no open flame, and safety and reliability.

[0077] It should be noted that when the user needs to connect to room temperature water, the instant heating device 25 is not in operation. In this way, even if water flows through the instant heating device 25, the electric heating element inside the instant heating device 25 will not heat the water flow, so that room temperature water flows out of the tankless water dispenser 2.

[0078] Please continue to refer to Figure 6 、 Figure 7 Further, in order to optimize the thermal management of the tankless pipeline machine 2, avoid unnecessary heat transfer superposition between the electric control device 24 and the instant heating device 25, a strong electricity installation area 214 and a weak electricity installation area 213 are arranged in the shell 21, wherein the electric control device 24 is installed in the weak electricity installation area 213, the instant heating device 25 is installed in the strong electricity installation area 214, and part of the power line 26 is installed in the strong electricity installation area 214. It can be understood that the electric control device 24 needs to be powered by weak electricity, and the weak electricity has the characteristics of low voltage and small current; the instant heating device 25 needs to be powered by strong electricity, and the strong electricity has the characteristics of high voltage and large current; the power line 26 needs to be electrically connected with the external power supply to supply power to the devices in the tankless pipeline machine 2, therefore, by arranging the power line 26 in the strong electricity installation area 214 and the electric control device 24 in the weak electricity installation area 213, heat coupling between the power line 26 and the electric control device 24 can be avoided, thereby avoiding damage to the internal devices of the electric control device 24, thus achieving protection of the electric control device 24 and the power line 26.

[0079] It should be noted that the weak electricity installation area 213 described above can be understood as an electric control installation area.

[0080] Please continue to refer to Figure 6 、 Figure 7 In some embodiments, the strong electricity installation area 214 includes an instant heating installation area 2142 and a waterway installation area 2141, and the waterway installation area 2141 is located between the instant heating installation area 2142 and the weak electricity installation area 213; that is, in the length direction of the tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged side by side, and a thermal isolation barrier is formed by the waterway installation area 2141 to separate the electric control device 24 and the instant heating device 25, thus reducing thermal energy interaction interference.

[0081] Please continue to refer to Figure 6 、 Figure 7 In some embodiments, part of the power line 26 is arranged in the waterway installation area 2141 to separate the power line 26 from the instant heating device 25; that is, in the length direction of the tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are arranged side by side, and since the instant heating device 25 and the electric control device 24 will generate heat during operation, the power line 26 close to the instant heating device 25 or the electric control device 24 will affect the power line 26, therefore, in the embodiments of the present application, the power line 26 is arranged in the waterway installation area 2141, and the waterway installation area 2141 is located between the instant heating installation area 2142 and the weak electricity installation area 213, thus reducing thermal energy interaction interference.

[0082] Please refer to Figure 8 and Figure 9In some embodiments, the water tankless pipeline machine 2 further comprises a water circuit system 22, which is arranged in the water circuit installation area 2141 and is electrically connected with the power line 26 and the electric control device 24, so that the power line 26 supplies power to the water circuit system 22, and the electric control device 24 is used to control the operation of some devices in the water circuit system 22; the water circuit system 22 is also in communication with the instant heating device 25, so that the instant heating device 25 can heat the water in the water circuit system 22 to achieve the discharge of hot water by the water tankless pipeline machine 2.

[0083] Please continue to refer to Figure 8 and Figure 9 In some embodiments, the shell 21 has a water inlet 211 and a water outlet 212, wherein the water inlet 211 is in communication with the pure water outlet 32 of the water purifier 3, so that the purified pure water from the pure water outlet 32 of the water purifier 3 flows into the water circuit system 22 after flowing into the water inlet 211, and then flows out from the water outlet 212 for use by the user.

[0084] Please refer to Figure 6 and Figure 8 The water circuit system 22 is arranged in the shell 21 to protect the parts in the water circuit system 22. The water circuit system 22 can include a first water inlet solenoid valve 2211 and a pump assembly 2212 arranged in sequence along the flow direction of the water flow, and the first water inlet solenoid valve 2211 is in communication with the water inlet 211. It can be understood that the first water inlet solenoid valve 2211 is used to control the entry of pure water of the water dispenser, and the first water inlet solenoid valve 2211 is closed or opened by the attraction and release of the electromagnet; the pump assembly 2212 is responsible for providing power to the water flow, and the water pump 2214 drives the impeller to rotate by the motor to generate centrifugal force on the liquid, thereby achieving the transportation of the water flow, and in this process, the voltage is used as the motor driving source; that is, when the voltage is large, the speed of the motor driving the impeller to rotate is fast, so that the speed of the water flow flowing through the water pump 2214 is accelerated, so that the flow of the water flow flowing through the water pump 2214 is larger, thereby achieving the adjustment of the flow of the water flow.

[0085] Further, the pump assembly 2212 is in communication with the instant heating device 25, the instant heating device 25 is in communication with the water outlet 212, and the electric control device 24 is electrically connected with the first water inlet solenoid valve 2211, the pump assembly 2212 and the instant heating device 25. When the user uses the water tankless pipeline machine 2 and needs to take hot water, the electric control device 24 can control the first water inlet solenoid valve 2211 to open, and the water pump 2214 and the instant heating device 25 to work, so that the water outlet 212 of the water tankless pipeline machine 2 discharges the water temperature and water volume required by the user, thereby achieving the discharge of hot water by the water tankless pipeline machine 2.

[0086] Please refer to Figure 6In some embodiments, the shell 21 further has a recess 216, the power cord 26 and the water inlet 211 connected to the first water inlet electromagnetic valve 2211 are located in the same recess 216; that is, the power cord 26 and the first water inlet electromagnetic valve 2211 are located in the same recess 216, so that when the shell 21 of the water tankless pipeline machine 2 is produced, another recess 216 does not need to be opened on other places of the shell 21, so that the production efficiency of the water tankless pipeline machine can be improved.

[0087] Please refer to Figure 10 、 Figure 11 In some embodiments, the pump assembly 2212 is a water pump 2214, and the waterway system 22 further comprises a negative pressure valve 2217 arranged between the first water inlet electromagnetic valve 2211 and the water pump 2214. It can be understood that the negative pressure valve 2217 is connected to the first water inlet electromagnetic valve 2211 and the water pump 2214 and is located between the first water inlet electromagnetic valve 2211 and the water pump 2214; that is, when the water flow in the waterway system 22 is cut off or the water pump 2214 stops working, the negative pressure valve 2217 can prevent negative pressure (i.e. pressure lower than atmospheric pressure) from being generated in the pipeline. Negative pressure can cause pipeline rupture, water hammer phenomenon (pressure impact generated due to sudden stop or change of direction of water flow) or other damage. The negative pressure valve 2217 can maintain positive pressure in the pipeline or at least prevent the generation of negative pressure, thereby protecting the water pump 2214, valves, pipelines and other components in the system from damage. The negative pressure valve 2217 can achieve the prevention of negative pressure generation in various ways, such as air supplement method, pre-pressurization method, etc. Furthermore, the negative pressure valve 2217 in the embodiments of the present application is a mechanical negative pressure valve 2217; that is, when the water tankless pipeline machine 2 is working normally, the first water inlet electromagnetic valve 2211 is opened, and the purified water filtered by the water purifier 3 flows from the purified water outlet 32 to the water inlet 211 and then flows into the first water inlet electromagnetic valve 2211, at this time, the water pump 2214 works, and negative pressure is generated at both ends of the negative pressure valve 2217, so that the negative pressure valve 2217 is opened to control the water flow from the negative pressure valve 2217. The specific structure and principle of the negative pressure valve 2217 have been disclosed in related technologies, and will not be described herein. Of course, in other embodiments, the pump assembly 2212 can be a flow control pump 2213, so that the negative pressure valve 2217 can not be arranged (see FIG. 6). The following will be described taking the pump assembly 2212 as the water pump 2214 as an example. Figure 9

[0088] Please refer to Figure 7 、 Figure 8 ​In some embodiments, the waterway system 22 further comprises a water quantity sensor 2215 electrically connected with the electric control device 24. The water quantity sensor 2215 can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, so that the water quantity sensor 2215 is in communication with the water inlet 211; or the water quantity sensor 2215 is arranged between the first water inlet electromagnetic valve 2211 and the water pump 2214, or the water quantity sensor 2215 is arranged between the water pump 2214 and the water outlet nozzle 212, so that the water quantity sensor 2215 is in communication with the water outlet nozzle 212. The present application does not make specific limitations on this. The water quantity sensor 2215 comprises two polar plates. When there is sufficient water in the waterway system 22 flowing through the water quantity sensor 2215, the water flow will flow through the two polar plates at this time, so that the water quantity sensor 2215 generates an electric signal and sends a changed signal to the electric control device 24. Since the electric signal generated by the water flow flowing through the two polar plates is inconsistent with the electric signal generated by the water flow flowing through the two polar plates when there is less air or water, the electric control device 24 can determine the water quantity in the waterway system 22 according to the received electric signal. It can be understood that when the instant heating device 25 is arranged in the water tankless pipeline machine 2, the instant heating device 25 is electrically connected with the electric control device 24. The water quantity sensor 2215 can protect the instant heating device 25. That is, when the user needs to use hot water, the instant heating device 25 works, but due to insufficient water in the waterway system 22, the electric heating element in the instant heating device 25 is exposed to the air and continuously heated, so that the instant heating device 25 is in dry burning, which leads to overheating of the instant heating device 25. Thus, the instant heating device 25 is easily burned out, and high-temperature steam is easily generated in the heating process of the instant heating device 25. If the water tankless pipeline machine 2 is used under the condition of insufficient water in the waterway system 22, high-temperature steam is easily sprayed at the water outlet nozzle 212, which can cause harm to the user. Therefore, the water quantity sensor 2215 arranged in the present application can monitor the water quantity information in the waterway system 22 in real time and feed back the monitored water quantity information in the waterway system 22 to the control device of the water tankless pipeline machine 2. The control device determines the water quantity in the waterway system 22 according to the set water shortage logic. When the water quantity in the water quantity system is lower than the preset threshold value, it indicates that the water in the waterway system 22 is insufficient. The control device controls the instant heating device 25 to stop working or reduces the power of the instant heating device 25 to prevent the occurrence of dry burning phenomenon, so as to protect the instant heating device 25 and ensure the safety of the water tankless pipeline machine 2, thereby achieving the protection of the water tankless pipeline machine 2. Furthermore, the water quantity sensor 2215 can achieve the effect of energy saving and power saving by intelligently controlling the power of the instant heating device 25, thereby reducing the electricity cost of the user.

[0089] Please continue to read Figure 7 、 Figure 8In some embodiments, the waterway system 22 further comprises a flow meter 2216 electrically connected to the control device 24. The flow meter 2216 can be arranged between the water inlet 211 and the first water inlet electromagnetic valve 2211, so that the flow meter 2216 is in communication with the water inlet 211; or the flow meter 2216 is arranged between the first water inlet electromagnetic valve 2211 and the water pump 2214, or the flow meter 2216 is arranged between the water pump 2214 and the water outlet nozzle 212, so that the flow meter 2216 is in communication with the water outlet nozzle 212. The present application does not make specific limitations on this. The flow meter 2216 is used to detect the flow of water flowing through the waterway system 22. That is, when the user inputs a quantitative water taking value to the water tankless pipeline machine 2, the first water inlet electromagnetic valve 2211 is opened, the water pump 2214 is working, and the flow meter 2216 starts to detect the flow of water flowing through the waterway system 22 and sends it to the control device of the water tankless pipeline machine 2. When the flow meter 2216 detects that the flow of water flowing through the waterway system 22 reaches the water taking value required by the user, the control device controls the first water inlet electromagnetic valve 2211 to be closed, and the water pump 2214 and the flow meter 2216 stop working. In this way, the present application can improve the detection of the flow of water flowing through the waterway system 22 and the accuracy of controlling the amount of water discharged by the water tankless pipeline machine 2 by arranging the flow meter 2216.

[0090] Please refer to Figure 8 and Figure 11 In some embodiments, the waterway system 22 further comprises a check valve 2218 arranged at the water outlet nozzle 212 to prevent water dripping from the water outlet nozzle 212. It can be understood that the waterway system 22 further comprises a water outlet pipeline 29 for connecting the instant heating device 25 and the water outlet nozzle 212. When the instant heating device 25 is used to heat the water in the waterway system 22, it is difficult for the instant heating device 25 to heat the water in the waterway system 22 to 100 degrees Celsius due to the rapid heating of the instant heating device 25. Therefore, the check valve 2218 arranged at the water outlet nozzle 212 in the present application can play a pressure bearing role to improve the boiling point of the water in the water outlet pipeline 29, so that the water boils. In the process of boiling water, water vapor can be arranged in the water outlet pipeline 29, and since the water outlet pipeline 29 is connected to the water outlet nozzle 212, the water outlet nozzle 212 can discharge water vapor, so that the water outlet nozzle 212 can flow out a stable water column.

[0091] Furthermore, the check valve 2218 can be equivalent to a one-way valve to prevent water flow from flowing backward in the water outlet pipeline 29, and to protect other components in the waterway system 22, such as the water pump 2214, the instant heating device 25, etc., from being impacted and damaged by the reverse water flow.

[0092] Please continue to refer to Figure 8 and Figure 11In some embodiments, the tankless pipeline machine 2 further comprises a sterilization device 23, which is arranged between the instant heating device 25 and the water outlet nozzle 212, or arranged upstream of the instant heating device 25, and the present application does not make specific limitations on this. It can be understood that the sterilization device 23 can effectively kill bacteria, viruses and other microorganisms in the water flow to ensure the safety and hygiene of the water quality, thereby improving the water quality of the tankless pipeline machine 2. The sterilization device 23 can be in the form of an ultraviolet sterilizer or an ozone sterilizer, and such sterilization device 23 can effectively sterilize without generating chemical residues, thereby reducing pollution to the environment; in addition, these devices are usually designed to be compact, easy to install and maintain.

[0093] Please refer to Figure 2 and Figure 11 In some embodiments, the tankless pipeline machine 2 further comprises an illuminating lamp 28 arranged on the housing 21 and facing the water containing area of the tankless pipeline machine 2, so that the light emitted by the illuminating lamp 28 illuminates the water containing area below the water outlet nozzle 212. It can be understood that the illuminating lamp 28 can provide auxiliary lighting for the water outlet nozzle 212, i.e. provide lighting for the water containing area below the water outlet nozzle 212, so as to facilitate the user to observe the water containing area in a dimly lit environment, and thus the user can accurately operate the tankless pipeline machine 2 based on the water outlet condition without the aid of additional lighting devices, reducing the risk of misoperation and safety hazards caused by blurred vision, improving the convenience of using the tankless pipeline machine 2, and providing additional protection for the user's water taking safety.

[0094] Furthermore, in order to ensure that the illuminating lamp 28 can effectively illuminate the water containing area below the water outlet nozzle 212, the illuminating lamp 28 is mounted on the housing 21 and at least partially protrudes from the housing 21, so as to ensure that the illumination side of the illuminating lamp 28 and the water outlet side of the water outlet nozzle 212 are consistent, so that the illuminating lamp 28 provides sufficient illumination range.

[0095] Please continue to refer to Figure 2 and Figure 11 In some embodiments, the tankless pipeline machine 2 further comprises a display device 27 arranged on the housing 21 to display the working information of the tankless pipeline machine 2. It can be understood that the display device 27 can be electrically connected with the electric control device 24, and the display device 27 can receive signals and data from the electric control device 24 and display the working information of the tankless pipeline machine 2, such as water outlet temperature, water outlet temperature, WiFi connection and the like. Further, the display device 27 can comprise a plurality of keys and a display screen, and the user can operate any key to make the tankless pipeline machine 2 perform corresponding functions and display the working information of the tankless pipeline machine 2 on the display screen.

[0096] In some embodiments, the display device 27 and the irradiation lamp 28 are both installed in the instant heating installation area 2142, so that the display device 27 and the irradiation lamp 28 can be located close to each other. Since the display device 27 and the irradiation lamp 28 are located close to each other, the display device 27 is electrically connected to the irradiation lamp 28 in the embodiments of the present application, the display device 27 is further used to supply power to the irradiation lamp 28 and directly control the opening and closing of the irradiation lamp 28, which helps to simplify the wiring complexity in the tankless pipeline machine 2.

[0097] The same or similar reference signs in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it is understood that if the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary illustration, and cannot be understood as a limitation of the present patent, for those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0098] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
